15 Claims.

My invention relates to hoisting means and more particularly to one foruse with building windows.

One of the objects of my invention is to produce an improved portablehoisting means which can be quickly and easily attached to a buildingwindow structure and employed for lifting articles, such as stormwindows, to and lowering them from an upper story. I

Another object of my invention is to produce an improved hoisting means,including a hoisting device, which can be fastened to a window sash forlifting and lowering a storm window, said device being so arranged thatthe pulley carrying projecting part can be movedout of the way duringinstallation of the storm window on its hangers and its removaltherefrom.

Still another object of my invention is to provide improved means forassociation with a window sash and a window frame for raising andlowering a storm window and for supportingflit adjacent the windowduring the hanging and unh'anging operations.

A still further object of myinvention is to provide portable-means foraiding in the installation and removal of storm windows which is simplein construction, economical to manufacture, and easily and safely usablein order to save labor and prevent damage.

Other objects of my invention will become apparent from the ir'ollowingdescription taken in connection with the accompanying drawing in whichFigure '1 is a view showing my improved hoisting and supporting means asassociated with a building window when being used as an aid ininstalling or removing storm windows; Figure2 is a sectional view takenon the line 2-2 of Figure 1 but showing the storm window resting on thesupporting means; Figure 3 is a top view showing details of the pulleyand its manner of mounting on the outer end of the arm of a hoistingdevice; and Figure iisa view of a modified hoisting device.

Referring in detail to the drawing, myhoisting means comprisesessentially three elements, namely, two like hoisting devices A and Band a supporting means C. The hoisting devices A and B are adapted to bemounted on the window sash frames and the supporting means C is adaptedto be associatedwith the sash and the bottom of the window frame whereit'is held in'position.

Each hoisting device comprises a U-shaped bracket I having'a baseportion 2 and legs3and 4. As shown, the bracket is made of wood with thebase portion and legs comprising separate members secured: together by.suitable means, such as: nails or screws.v Associatedxwith the bracketis an arm 5. shown as formed of :three wooden members 6, l, and 8arranged in the shape of a right-angle with members at and 8 positionedat. right-angles to each. other "and member connectedbetween themembersSand :8 and arranged to form the brace of the arm.

The armis' pivotally connected to bracket l' by-a hinge 9, said hingebeing connected 1170 the base member 2 of the bracket andmember 6-ofthearm .so that/the arm canassume a position wherethe member 8cooperates with leg 4 of the bracket and extends 'outwardlyfrom thebracketas; shown in Figures 1 and 2. The "hinge. connectionpermits thearm toz-be swung about the-bracket to a position where'the armwilloverlie thebase of the bracket, that is, memberB of .the arm and thebasemember 2 of the bracket will be injuxtaposition. The outer end ofthearm attheil'uncture of the-membersfi and l carries a pulley Ill whichis positioned in a slot II, the pulley being journaled on a bolt I12; Ametal rerenforcing member I3 is positioned over the joined ends ofmembers 6 and 1 and thus'maintains thesemembers together and alsoprovidesa wear resisting bearing for the bolt I2. the pulley and has asnap l5 secured .to oneend.

When devicesA and Bare to bemountedupon the Window, the upper sash frame16 thereof lowered in window frame [-1 to its-fullest extent so that itis positioned alongside thelower sash frame l8. With thesepositions thetops ofboth sash frames are together. so that. the. U -shaped bracket Iof the hoisting device. may beinverted and slipped over these ends atthe side of the sash frame so that. the legs will extend downwardlyalong the side framev member of each sash- When the hoisting means is tobe used, the arm "5 of each hoisting device. is swung outwardly to the,positionshown inf Figure 2so that the outer end of the armandpulley willbe away from the building. To raise or lower a storm sash the snaps l5on the cords are attached to the hangers l.9 of the storm windowill. Ifthe storm window is on the ground, itcan be raised up to the window by,pulling on the. cords. If it is already up atthe window,it can belowered to the ground by means of the cords.

Duringthe installingof the storm window on the hooks 2 I atthe'top ofthe window'frame and removing it therefrom, it is desirable to have asupport for the storm window'so'asto permit easy attaching and detachingof the cords "to A cord l4 passes over I the storm window hangers. Thissupport is provided by the previously mentioned supporting means C whichis so constructed as to be readily associated with the window. As bestshown in Figure 1, the supporting means comprises two members 22 and 23,such as strips of wood, which members are pivoted together by a hinge24. The free end of the member 23 carries a rest 25 having a brace 26associated therewith. The supporting means is placed in position bymerely placing member 22 across the center of the bottom member 2! ofthe window frame so that the members 23 can hang downwardly alongsidethe building below the window sill. The supporting means is maintainedin position by the two window sashes when in their lowered positions, itbeing noted that member 22will then be held between the bottom member2'! of the window frame and the bottom frame members of the windowsashes. The member 23 of the supporting means is of such length thatwhen the bottom of the storm window is positioned on the rest 25, thetop of the storm window will be just below the arms of the hoistingdevices.

With this supporting means it is seen that when the storm window isbeing hoisted from the ground for installation, the bottom thereof canbe positioned on the supporting rest 25 after the storm window has beenpulled up to where the top of the storm window is just beneath the arms.

With the storm window in this position it is not necessary for theperson installing the storm window to support it by his own strengthand, therefore, he will be free to unsnap the cords from the hangers IQof the storm window. When this is done, each of the arms can be swungback out of the way to the position shown in dashed lines in Figure 2.With the arms out of the way they cannot interfere with the actualhanging of the storm window. To install the storm window theperson needonly reach over the top of the two lowered sashes andgrasp the stormwindow on each side intermediate its ends. He is then in a good positionto raise the storm window through a distance approximately half itslength and to then place the hangers IS on hooks 2|.

In-removing a storm window the operation is reversed. ated with thewindow and then the hoisting de- The supporting means is firstassocivice is mounted on the window sashes with the u per sash inlowered position. The arm A will be placed in the dashed line position.The storm ,window is then unhooked and its bottom posibracket so it canbe used with either size. To accomplish this the bracket l is made sothat the space betweenlegs 3 and 4 will fit the thicker sash frames.When the bracket is to be used with the thinner sash frames, a block 28is proyided which is attached to the inside of leg 3, as

'indicated by dashed lines in Figure 2.

From the foregoing description of my hoisting means, it is seen that astorm window can be very easily and quickly installed or removed from anupper story window frame. tall laddersfor hanging or the carrying of the,storm' window through the house and boosting The use of itthroughthe'window are both eliminated by the use of the hoisting means.By using the hoisting means, handling is reduced to a minimum, thusdecreasing the possibilities of glass breakage. There is also aconsiderable saving in labor as it permits the storm window to be easilyraised to an upper story window or lowered therefrom. When the stormwindow is at the upper story window and positioned on the rest of thesupporting means C, it is in a good position for proper grasping toplace the hangers on the hooks.

In Figure 4 there is shown a hoisting device which can be made frommetal. The bracket I is made of a single member formed in the shape of aU with a base portion 2' and legs 3 and 4', the leg .4 having anoutwardly extending projection 29. The arm 5 is also made of a singlepiece of metal bent in the form of a V with'the leg portion 6' pivotedto the bracket I by a pivot pin 9' and the other leg portion 1' actingas the brace with its end adapted to abut the leg 4' of the bracket andto be retained in position by the projection 29. The pulley is mountedon the end of the arm by a bolt 30. The hoisting device is used in thesame manner as the one previously described.

Being aware of the possibility of modifications in the particularstructure herein described without departing from the fundamentalprinciples of my invention, I do not intend that its scope be limitedexcept as set forth by the appended claims.
